Triptycene derivatives for use in electroluminescent devices

摘要

Triptycene derivatives are useful in electroluminescent devices. The use of triptycene derivatives of formula (I) in electroluminescent devices is claimed: K<1>-K<3> = optionally substituted mono- or polycyclic systems which may also contain hetero atoms; X, Y = CR<1>, N, P, As or SiR<2>; R<1> = H, halogen, pseudohalogen or 1-30 C hydrocarbyl (optionally containing hetero atoms); R<2> = 1-30 C hydrocarbyl (optionally containing hetero atoms). Independent claims are also included for: (a) compounds (I) as such in which at least one of the groups K<1>-K<3> is a fluorophore; (b) electroluminescent devices containing one or more active layers, at least one of which contains one or more triptycene derivatives (I).
